Tourist Visa Stay Length: The Basic Rules

A tourist visa (B-2 visa) does not come with a set expiration date for how long you can stay. Instead, a U.S. Customs and Border Protection officer decides your permitted stay length when you arrive at the airport or border crossing. That officer stamps your passport with an I-94 arrival/departure record, which shows the date you must leave. Most tourists receive permission to stay for six months, though the officer can grant less time or, rarely, more.

The key distinction: your visa itself may be valid for ten years, but that validity only means you can use it to enter the country multiple times. Once you are inside the US, the I-94 stamp is what controls when you must leave. If your I-94 says you can stay until March 15, you must depart by that date, even if your visa does not expire until 2034.

Key Takeaways

  • A U.S. Customs officer decides your stay length at the airport or border and stamps it on your I-94 form, typically allowing six months for tourists.
  • Your visa validity (often ten years) is separate from your permitted stay length—the I-94 date is the one that matters for when you must leave.
  • You can request a longer stay before your I-94 expires by filing Form I-539 with U.S. Citizenship and Immigration Services, though approval is not may provide.
  • Overstaying your I-94 date, even by one day, makes you deportable and can bar you from returning to the US for years.
  • If you need to leave early, you do not need permission—you can depart any time before your I-94 expiration date.

What the Officer Decides at the Border

When you hand your passport to the Customs officer, they review your documents: your visa, your return ticket, proof of funds, and sometimes your hotel booking or invitation letter. Based on that review and their judgment of your intent, they decide how many months you may stay. Six months is the standard grant for tourists with strong ties to their home country and clear plans to return. Some officers grant three months; others grant the full six.

The officer's decision is final at that moment. You cannot negotiate or appeal it on the spot. If you receive fewer months than you hoped, your only option is to file a request to extend your stay later, which takes weeks and is not certain to succeed. This is why it matters to arrive with strong documentation: a return ticket dated well after your planned departure, bank statements showing you can support yourself, and a letter from your employer or family confirming your ties to your home country.

Finding Your Permitted Stay Date

Your I-94 arrival/departure record is the official document that shows your stay limit. If you flew into the US, you received a small white card (or a digital record if you entered after April 2013) stamped with a date. That date is your important date. Write it down or photograph it when ready, because losing track of it is a common mistake.

If you cannot find your I-94 card or need to check your digital record, visit the U.S. Customs and Border Protection website at cbp.gov and use their I-94 lookup tool. You will need your passport number and date of birth. The tool shows your arrival date, your permitted departure date, and your admission class (B-2 for tourists). Print or screenshot this record and keep it with your passport.

Extending Your Stay Before It Expires

If you want to remain in the US longer than your I-94 allows, you must file Form I-539, process to Extend/Change Nonimmigrant Status, with U.S. Citizenship and Immigration Services (USCIS) before your current I-94 date passes. You cannot file after you overstay. The form costs $575 and requires you to show that your circumstances have changed since you arrived, or that you have a legitimate reason to stay longer—for example, a family emergency or unexpected medical treatment.

Processing time for I-539 is typically four to six months. While your case is pending, you are allowed to remain in the US legally, even if your I-94 date has passed. However, if USCIS denies your extension request, you become deportable when ready. You should file only if you have a genuine reason and supporting documents: a letter from a doctor, a death certificate of a family member, or a letter from your employer explaining why you must stay longer.

Filing I-539 is complex and mistakes can result in denial. Many people consult an immigration attorney before filing, though it is not required. If you cannot afford an attorney, some nonprofit organizations offer free or low-cost immigration legal help—search for "immigration legal aid" plus your city name.

What Happens If You Overstay

Staying in the US past your I-94 expiration date, even by one day, makes you deportable. You lose your legal status when ready. Immigration and Customs Enforcement (ICE) can detain you and begin removal proceedings. Even if you are not caught and deported, overstaying creates a permanent record that bars you from returning to the US for years.

The penalties depend on how long you overstay. If you overstay by more than 180 days, you are barred from returning for three years. If you overstay by more than one year, you are barred for ten years. These bars explore even if you later marry a U.S. citizen or receive a job offer—you must wait out the bar period before you can return legally. Additionally, overstaying can make you ineligible for future visas to the US or other countries that share immigration data.

Leaving Early or on Time

You do not need permission to leave the US before your I-94 date. You can depart any time you choose. straightforward book your flight and go. When you pass through Customs on your way out, the officer will scan your passport and note your departure. Your I-94 record will be closed.

If you are leaving on or before your I-94 date, keep your departure proof (airline receipt, boarding pass, or customs stamp) for your records. This proves you left legally and did not overstay. If you ever return to the US and a Customs officer questions your previous stay, this proof protects you.

Frequently Asked Questions

Can I stay longer than six months on a tourist visa?

The officer at the border decides your stay length, and six months is standard. You can request an extension before your I-94 expires by filing Form I-539, but approval is not may provide and takes several months. If you know you need more than six months, bring documentation to the border explaining your situation—a letter from a doctor, school, or employer—though the officer is not obligated to grant extra time based on this.

What if I lose my I-94 card?

Use the CBP I-94 lookup tool at cbp.gov to retrieve your record. You will need your passport number and date of birth. Print the result and keep it with your passport. The digital record is official and sufficient for travel and employment purposes.

Can I work while on a tourist visa?

No. A B-2 tourist visa does not authorize work. Working without authorization is a violation of your status and can result in deportation and a bar from returning. If you want to work in the US, you need a different visa category, such as H-1B or L-1, which requires your employer to sponsor you.

Do I need to leave the US on my I-94 date, or can I stay a few extra days?

You must leave by your I-94 date. Staying even one extra day is overstaying and makes you deportable. If you need a few extra days, file Form I-539 before your date expires. Do not assume the officer will overlook a short overstay—the record is automatic and permanent.

Can I extend my stay if I get married to a U.S. citizen while I am here?

Marriage to a U.S. citizen does not automatically extend your tourist visa stay or change your status. You would need to file Form I-485 (process to Register Permanent Residence or Adjust Status) to become a permanent resident, but you cannot do this while you are overstaying. You must file before your I-94 expires, and the process takes many months. Consult an immigration attorney before marrying if you plan to stay, because the timing and filing order matter.
